The basic ideas of the Left come from the realities of the 18th and 19th centuries. Ideas, such as class struggle, offered a plausible explanation of reality given the facts of past centuries. The paradigm of the Left also offered a roadmap for how to improve the world given a particular set of facts. Those facts, though, have changed. The Left, then, is faced with a new set of facts that their basic paradigm is unable to explain and therefore is unable to inform the believer on how to improve social conditions. The theory no longer is able to inform us as to how to make decisions. All we are left with is a paradigm of criticisms. The last gasping breath of a dying ideology.
